Your cht parameter is specifying an "lc" line chart which is "a line chart where data points are spaced evenly along the x-axis." To have power over the exact x-coordinate, switch to the "lxy" line chart which "lets you specify both x- and y-coordinates for each point, rather just the y values."
Here's an example of taking an equally spaced line chart and adding x- coordinate values: http://chart.apis.google.com/chart?chs=350x200&cht=lc&chd=t:42,43,42,44,53,57,56,53,52,51&chm=o,000000,0,-1,10 http://chart.apis.google.com/chart?chs=350x200&cht=lxy&chd=t:0,10,20,30,80,84,88,92,96,100|42,43,42,44,53,57,56,53,52,51&chm=o,000000,0,-1,10 Hope that helps, Keith -- You received this message because you are subscribed to the Google Groups "Google Chart API" group.
